Specification of Letters Patent. Application filed June 6,1906. seria1N 's2o,426.

Patented Aug. 6, 1907.

To all whom it may concern:

Be it known that I, KARL O. MUEnLBnRo, a resident oi Homestead, in the county of Allegheny and State of.

Pennsylvania, have invented a new and useful Im provement in Hose-Couplings; and I do hereby declare the followingto be a full, clearfland exact description thereof. I

This invention relates to hose connectors and its object is to providea device of this character which is simple of construction and will tightly and securely clamp the end of the hose, and which is so constructed that a connector of given size is adapted to hose of severaldiffcrent sizes, or to :hose having walls of several different thicknesses. a I

The invention consists, generally stated,-in providing removable and interchangeable spacing a'ndclamping rings or members which are or several different sizes internally to fit hose of several different external sizes and all of which rings are of the same external size so as to fit into the one connector.

In the accompanying drawings Figure 1 is a longitudinal section through one form of my hose connector, showing the hose clamped in place; Fig. 2 is a similar view showing a hoseIhaving a thicker wall, and also.

showing a slightly difierent'iorm oi nipple.

My hose connector comprises a suitable body. 1 provided with the bore or ofp'ening Z, as ishsual, and at one end provided with a nipple 3 whichis tapering or-c'onical, either on a straight taper, as shown in 1 ,'or on a rounded taper, as shown in Fig. 2. The body has its largest portion threaded externally,

as at 5 and working on this threaded portion is the internal threaded sleeve or nut 6 which at its outer end'is provided with an inward-1y projecting shoulder, such as the flange 7, said sleeve being arranged outside of the hose 8, andthe end of the latter fitting over the nipple3. The opening- 9, in the outer end of the sleeve 6 is considerably larger than the hose, and the latter is clamped by means of the ASSIGNOR TO PITTSBURGH HOSE i removable and interchangeable spacingand clamping correspond approximately with the bevel of'the nipple '3, althoughthis is not absolutely necessary as the same may be square, as shown in Fig. 2. v

vided for each size of hose connector, these clamping rings for a given connector all being ofthe same size externally but having openings therethrough of differ ent sizes. The bodies of the cpnnectors shown in Figs. l and 2 are of the same size also of the sameexternal size, butha've openings of difi erent sizes so as to clamp hose having walls of materially different thicknesses, as'shown in the two-figures; -By using a suitable number, say three or four, interchangeable clamping rings for each size of connector the latter is adapted to quite a variety of sizes or thicknesses of walls of hose, as will be readily apparent.

What I claim is: A hose connector comprising a tubular body provided with external threads andhaving on the end a tapering or conical projection designed to enter the hose, an internally threaded sleeve adapted to encircle the hose and engaging the thread of the body and having at its outer end an internal shoulder, and a removable and interchangeable spacing and clamping ring in said sleeve arranged to be engaged by the internal shoulder thereof, the opening jection on the body and adaptedto receive the hosbetween'the same and said body projection.
